Placed between cathode and anode to control the volume of electrons.
A (or thermionic valve) is an electronic component that controls electric current flow within a high-vacuum sealed container. Primarily used in early electronics, they amplify, switch, or regulate signals by controlling the movement of electrons emitted from a heated surface. Core Components vacuum tube
Include additional grids to improve efficiency and reduce signal distortion. Placed between cathode and anode to control the
Positively charged electrode that attracts the electrons. vacuum tube
Introduced the grid for amplification.
